JOHN R. WILLIAMS, OF MILWAUKEE, WISCONSIN.

CATCH-BASIN AND TRAP.

To all whom it may concern:

Be it known that I, JOHN R. IVILLIAMS, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofVisconsin, have invented certain new and useful Improvements inCatch-Basins and Traps; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in catch basins and traps forcellar drainage and has for its object the production of a simple andefficiently operating device of this kind which may be installed inposition with great facility.

A further object of the invention is to so construct the device thatdirt or sediment will be kept out of the trap thus obviating thenecessity of frequently removing the trap and the attendantobjectionable features resulting therefrom.

A further object of the invention is to so construct the device that inthe event of dirt or sediment eventually collecting at the bottom of thetrap, the same may be removed in an. expeditious manner and with butslight inconvenience.

With these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts, aswill be more fully described and particularly pointed out in theappended claims.

In the accompanying drawings, Figure 1 represents a central verticalsection of the device as applied in position, Fig. 2 is a horizontalsection taken on line 22 of Fig. 1.

As shown in the drawings, this device embodies an upright body or casing1 provided with a removable perforated cover 2.

The numeral 4 indicates the trap, the upper end of which projects asuitable distance within the casing and is provided with an annularsediment chamber 4: formed by a transverse partition 4? provided with acentral tubular extension 4 This trap is of somewhat less diameter thanthe casing and is arranged at one side thereof or eccentric therewith, aportion of the wall of the upper end of the trap cooperating with aportion of the wall of the casing to provide a crescent-shaped sedimentchamber 6 (see Fig. 1). A bell-shaped deflector 7 is arranged in thesediment chamber 4, said deflector hav- Specification of Letters Patent.

mg a handle 8 which extends through and above a perforated cover 3closing in the upper end of the trap. The waste pipe 9 extends into thetrap below the partition 4" thereof, the inner projecting end of thewaste pipe having an outwardly opening fiap valve 9 which permits thedischarge of the Water through the waste pipe but prevents back How, ofthe water or gases into the trap. The lower end of the trap, as shown,extends a suitable distance below the waste pipe and is adapted toreceive any sediment that may eventually overflow the chamber 4.

In practice, the waste water passes through the perforated cover 2 ofthe casing and thence through the cover 3 of the trap through thepassage 10 between the upper end of the tubular extension 4: and thedeflector 7 into said extension and then through the waste pipe 9, thegreater portion of the sediment collecting in the chamber 6 of thecasing and the remaining portion being deflected by the deflector 7 intothe chamber 4:. In this manner the sediment is kept out of the wastepipe and liability of the same becoming chocked up is obviated. In theevent of the sediment eventually filling the chambers l and 6respectively, it will collect at the bottom of the trap from which itmay be removed by removing the covers 2 and 3.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention, as defined in theappended. claims.

Having thus described my invention, what I claim as new is 1. A deviceof the character described comprising an upright casing, a trap arrangedeccentrically within and projecting below the casing, a transversepartition provided with. a central upright tubular extension formed inthe trap, a waste pipe extending into the trap below said partition andan outwardly opening check valve arranged in the waste pipe.

2. A device of the character described comprising a cylindrical casing,an upright cylindrical trap arranged eccentrically with and extendingthrough the bottom of the casing, leaving a crescent-shaped spacebetween a portion of the outer surface of the upper projecting end ofthe trap and a portion of the inner surface of the casing, a transversepartition provided with a central upright tubular extension formed inthe trap, a bell-shaped deflector arranged in the upper end of the trapand surrounding the upper end of the tubular extension, a waste pipeextending into the trap below the partition thereof, and an outwardlyopening check valve in the waste pipe.

8. A device of the class described comprising a casing, a removableperforated cover arranged over the upper end thereof, a trap extendingthrough the bottom of the casing, a partition provided with a centraltubular extension formed in the trap, a removable perforated coverarranged over the upper end of the trap, a bell-shaped deflectorarranged in the upper end of the trap and surrounding the upper end ofthe tubular extension, said deflector having a handle portion projectingthrough and above the trap cover, a waste pipe extending into the trapbelow the casing and a check valve arranged in the waste pipe.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
